Analyst Ratings

Analyst ratings are opinions issued by Wall Street research analysts about whether a stock should be bought, held, or sold. Common rating scales include Buy/Hold/Sell, Overweight/Equal-Weight/Underweight, and numbered scales (1-5). Analysts also publish price targets representing where they expect the stock to trade over the next 12 months. Rating changes — especially upgrades and downgrades — can cause significant stock price reactions and create opportunities for options traders.

Why It Matters

Analyst ratings move stocks. An upgrade from a major firm (Goldman Sachs, Morgan Stanley, JP Morgan) can push a stock up 3-5% in a single day. A downgrade can do the opposite. For options traders, these moves create both risk and opportunity. If you hold short options on a stock that gets downgraded, the sudden move can push your position into loss territory. If you anticipate a rating change, options provide leveraged exposure to profit from it.

More broadly, the consensus rating (the average of all analyst opinions) and changes in that consensus provide useful sentiment data. When analysts collectively shift from bullish to neutral on a sector, it signals a change in institutional sentiment that options traders should consider.

How It Works

Types of rating actions:

• Initiation: An analyst begins covering a stock for the first time. Impact depends on the firm's reputation and the initial rating.
• Upgrade: Raising the rating (e.g., Hold to Buy). Typically bullish for the stock price.
• Downgrade: Lowering the rating (e.g., Buy to Hold). Typically bearish.
• Price target change: Raising or lowering the target price without changing the rating. Smaller impact but still moves stocks.
• Reiteration: Maintaining the same rating and target. Minimal impact.

How much do ratings move stocks?

• Major firm upgrade on a large-cap stock: typically 2-5% move
• Major firm downgrade: typically 2-7% move (downgrades tend to have larger impact)
• Small firm rating changes: typically 0-2% move
• Pre-market upgrades/downgrades: stock often gaps before options markets open

The bias in analyst ratings: Wall Street research has a well-documented bullish bias. Roughly 55% of ratings are Buy/Overweight, 35% are Hold, and only 10% are Sell/Underweight. This means:

• An analyst rating a stock "Hold" is often implicitly bearish
• A downgrade from Buy to Hold is a meaningful negative signal
• Sell ratings are rare and should be taken seriously — the analyst is making a strong contrarian call

Using analyst ratings in options trading:

• Watch for cluster downgrades (multiple analysts downgrading in sequence) — this signals a fundamental shift
• Before earnings, note whether the consensus has been upgraded or downgraded recently — this sets the bar for expectations
• After a downgrade, IV often rises, creating opportunities for premium sellers after the initial move
• Use price targets as reference points for strike selection on spreads

Limitations:

• Analysts have conflicts of interest (their firms may have banking relationships with covered companies)
• Ratings are lagging indicators — by the time an analyst upgrades, the stock may have already moved
• Price targets are wrong more often than right
• Consensus shifts slowly and often misses turning points

Quick Example

Stock UVW trades at $90. A top-tier analyst upgrades it from Hold to Buy with a $110 price target. The stock gaps up 4% to $93.60 at the open.

If you anticipated this upgrade (perhaps because the stock recently reported strong earnings that the analyst had rated Hold on), you could have bought a $92.50 call for $2.00 the day before. At the open, with the stock at $93.60 and elevated IV from the event, that call is worth approximately $4.00 — a 100% gain.

After the initial move, IV normalizes over the next few days. If you believe the stock will continue toward the $110 target, you sell a put spread: short $90 put, long $85 put, collecting $1.50. Your thesis is supported by both the upgrade and post-earnings momentum.
