The fact that a great stock can still be a bad investment at the wrong price prevents many investors from building wealth. Here are four genuinely great companies I wouldn’t buy at current prices: 1. $ARM Current price: $269 - Trades at roughly 279x P/E - More than 50x P/S prices in near-perfect execution - Great technology does not justify every valuation 2. $VRT Current price: $244 - Trades at roughly 55x P/E - Forward P/E remains above 30x - P/S expanded from ~0.9x to over 8x 3. $ANET Current price: $201 - More than 60x P/E for an established networking business - Nearly 24x P/S demands years of exceptional growth - Limited margin of safety if AI spending normalizes 4. $PLTR Current price: $176 - Trades at roughly 150x P/E - 93x Forward P/E already prices in extraordinary execution - Any growth disappointment could trigger severe multiple compression
