AI and Chip Stocks Falling: Should You Panic Sell? What to Check First

Start With Your Exposure

List the AI, chip, cloud or data-centre shares you own directly. For each sector or broad-market fund, use its factsheet or holdings list to see whether those companies also appear and how large the holdings are. A fund’s name does not tell you how concentrated its holdings are. YFD’s GICS and sector ETF guide explains why a sector label can hide concentration.

Direct portfolio impact ≈ starting portfolio weight × security loss

If a share starts at 8% of your portfolio and then loses 40%, the direct effect is 3.2% of the portfolio’s starting value, assuming all other holdings stay unchanged. This arithmetic excludes fees, tax and currency changes. Correlation affects combined portfolio risk, not this multiplication. Your total exposure through funds can add to the direct amount.

Measure the Price Move

You can describe the fall without predicting what comes next. The signed return is (current price ÷ prior peak) − 1. Drawdown magnitude, stated as a positive number, is (prior peak − current price) ÷ prior peak. A 30% fall needs a 42.9% gain from the lower price to recover. That is arithmetic, not a signal about value or future direction.

For a broad-market reference, Capital Group’s S&P 500 data through 31 December 2024 show declines of 10% or more about once every 18 months on average. The frequency calculation assumes the index recovers half the loss. This is a broad-market historical average, not a yearly schedule or forecast, and it does not predict AI or semiconductor shares. Capital Group explains the series here.

Check What Changed in the Business

Chip designers, foundries, equipment makers, cloud providers and data-centre operators have different capital needs, cash cycles and debt loads. Compare an issuer with its own history and relevant peers. A ratio that makes sense for one type of business may not suit another.

For a U.S.-listed issuer, read its latest Form 10-K or 10-Q. Check the business description, risk factors, Management’s Discussion and Analysis (MD&A), income statement, balance sheet, cash-flow statement, and debt and maturity disclosures. For a Malaysian or other non-U.S. issuer, use the equivalent annual and interim reports.

Look for changes in sales, earnings guidance and demand. Compare planned capital spending (capex) with expected revenue, operating cash flow, customer commitments, funding sources and the use of new capacity. Capex pays for long-lived assets such as data centres, chip plants and equipment. A large plan may support growth, but it also raises the funding need if demand or financing weakens.

An issuer may report orders, backlog, remaining performance obligations or contracted revenue. Check how it defines those amounts, when they may turn into revenue, and whether customers can cancel or defer them. These figures do not necessarily represent cash already received or revenue already recognized, and they do not guarantee future revenue. CEA Industries’ 2024 Form 10-Q is an example from a different industry. It explains that backlog and remaining performance obligations may not predict operating results, and conversion can be delayed or uncertain. It is not evidence about AI or semiconductor companies.

Start with operating cash flow

The cash-flow statement shows how much cash operations generated during a period and how much the company spent on long-lived assets. Free cash flow (FCF) is commonly estimated as same-period GAAP operating cash flow less capex. The SEC notes that FCF has no uniform definition and is not necessarily cash left after required debt payments or other spending.

Operating cash flow includes working-capital changes. The FCF number alone does not explain when cash came in or went out, why it changed, or what asset sales contributed. Read it with the cash-flow statement and the issuer’s own definition. Negative FCF can reflect investment for growth. Check how long the funding need may last and whether cash, borrowing or new shares can cover it.

Optional deeper check: funding ratios

You do not need to calculate every ratio for a first review. If the filings leave you unsure whether cash and earnings can carry planned spending and debt payments, these measures can add context:

EBIT is earnings before interest and tax. EBITDA is earnings before interest, tax, depreciation and amortisation. EBITDA is not cash; it leaves out interest, tax, working capital and capex. Adjusted EBITDA and lease treatment can differ by issuer. These ratios are screening tools, not universal danger lines. Use consistent periods and definitions, compare ratios over time and with relevant companies, and read them beside the debt schedule. Restricted cash, future cash flow and refinancing access affect whether cash can meet maturities. The CFA Institute’s financial-analysis guidance explains why ratios need comparison and context.

Optional deeper check: debt ratings and CDS

A rating on an issuer’s debt can help you assess its ability to pay, but it is an input, not a guarantee or a substitute for filings. A credit-default swap (CDS) transfers specified credit risk. Its spread is the market price of protection and includes risk-premium effects. A quote may be missing or illiquid, so use CDS data only when they are liquid and comparable. Do not read a spread as a direct default probability. The cited ECB study covers crisis-era banking and counterparty risk, not current technology issuers.

Compare Earnings Assumptions With Price

Warren Buffett wrote in Berkshire Hathaway’s 1989 shareholder letter: “It's far better to buy a wonderful company at a fair price than a fair company at a wonderful price.” Read the official letter. Treat it as a valuation principle, not a reason to buy simply because a share price is falling.

For a profitable company, share price ≈ forecast earnings per share (EPS) × price-to-earnings (P/E) multiple. For a share quoted in U.S. dollars, use USD forecast EPS and the P/E for the same forecast period. If both inputs fall 20%, their product falls to 80% × 80% = 64% of its prior value, a 36% decline. This is arithmetic, not fair value, a target or a forecast.

A lower P/E is not automatically a bargain. It may reflect slower growth, weaker earnings quality or higher risk. P/E may not help when earnings are negative or distorted. Compare relevant peers, consider another valuation method and state the assumptions. For an AI-related issuer, test whether expected revenue and cash flow support capex, then look for confirmation across results, guidance and financing disclosures.

Use Chart Measures as Context

You can follow the business and funding checks without drawing a chart. If you use chart measures, treat them as observations about price and trading activity, not a verdict on the company.

Optional deeper check: volume, breadth and moving averages

Trading volume is the number of shares traded over a period. Compare it with the same security’s history; volume alone does not show net buying or selling and cannot forecast direction. A 50-session simple moving average (SMA) is the mean closing price across the latest 50 sessions; a 200-session SMA uses the latest 200. Market breadth is the count or share of index constituents participating in a rise or fall. One measure is the share trading above their own 200-session averages.

Relative performance compares an asset’s return with a benchmark over the same start and end dates, using the same price-return or total-return basis. A sector can lose value but outperform if its loss is smaller. Check breadth and whether a few large holdings dominate a sector ETF. The YFD GICS and sector ETF guide explains why a sector label can hide concentration.

A moving-average break is not proof of fundamental damage, and an average is not guaranteed support. Keep any pre-set price-risk rule separate from your review of the business.

Write down what changed, which filing or market measure supports it, and what evidence would make you revisit the view.
