Buying a stock simply because it tops the gainers list is one of the most common mistakes among new traders. Momentum can continue, but the risk-reward often deteriorates after a large move.

Mean reversion

Extreme single-day gains often partially reverse as early buyers take profits. Chasing a stock up 15–20% without a plan frequently leads to buying near the short-term top.

Low liquidity traps

Small-cap and penny stocks can show huge percentage moves on tiny volume. Slippage on entry and exit can erase paper profits. Check traded quantity before acting.

News vs. noise

Verify why a stock is moving. Unverified social media tips, operator-driven moves, and circular trading have burned many retail participants. Prefer stocks with clear, verifiable catalysts.
