How do I know if a price is a good entry point?
Compare the price to what the company earns and to its own history and peers, not to where it was last month. For a long-term holding, the entry price matters far less than whether the business grows.
The trap here is anchoring on recent prices. A stock that was $200 last month and is $150 today feels cheap, but $200 may have been the wrong number. The question that matters is whether $150 is reasonable for what the company earns and how fast it is growing, which is what the P/E ratio and its comparison to peers is for.
A quick sanity check: look at the P/E against the company’s own five-year range and against a couple of direct competitors. If it is in the normal range for a business of that kind, the price is fine. If it is far above, you are paying for expectations that need to come true. If it is far below, ask why the market is so gloomy before assuming it is wrong.
For a long-term hold, the entry point matters less than people think. Studies of investors who bought the S&P 500 on the single worst day of each year still ended up with returns close to those who bought on the best day, because the years of growth after the purchase dwarfed the difference at the start.
If you cannot decide, split the purchase: half now, half in a month or two. It removes the fear of picking the exact wrong day, which is the fear that keeps most people from ever buying.
