PEG
N/A
P/E divided by EPS growth — under 1 = cheap
Trailing P/E uses the last 12 months of actual reported earnings — it is the most reliable number because the inputs have already happened. Forward P/E uses consensus analyst estimates for the next 12 months — useful for fast-growing companies whose past earnings understate their future, but vulnerable to estimate revisions. The PEG ratio (P/E divided by earnings growth) is the bridge: a PEG below 1.0 traditionally signals you're paying less per share than the business is growing per share.

Interpreting PTTEP-R.BK's P/E
What "Cheap (deep value)" means here: Trading below 10x earnings is the historical deep-value zone. Often signals either a genuine bargain or that earnings are about to fall — verify with cash flow and the Quality Triple Check.
Decision rule: a low P/E by itself is not a buy signal. Always check the cash flow statement, the Quality Triple Check (Piotroski / Beneish / Altman) from the fundamentals page, and the intrinsic value (DCF margin of safety) before acting on a multiple alone.
Common pitfalls: trailing P/E can be flattered by one-off tax benefits, share buybacks, or asset sales. Forward P/E can be overstated by overly optimistic analyst estimates. Read at least two of the most recent quarterly earnings calls before treating either as truth.

What is the difference between trailing and forward P/E?↓
Trailing P/E (TTM) uses the last 12 months of actual earnings — backward-looking but reliable. Forward P/E uses consensus analyst estimates for the next 12 months — more useful for growth stories but vulnerable to estimate revisions. Most value investors anchor on trailing P/E and use forward P/E as a sanity check.
How is P/E related to earnings yield?↓
Earnings yield = 1 / P/E. For PTTEP-R.BK at 10.0x P/E, earnings yield is roughly 10.02%. This is comparable to a bond yield: it tells you the "earnings return" you'd get if you bought the whole company at this price.
When is P/E the wrong metric to use?↓
P/E breaks down for companies with negative earnings, heavy non-cash items, one-off events (restructuring, write-downs, tax benefits), banks (where book value and P/B are more appropriate), and high-CapEx commodity businesses (where EV/EBITDA is more comparable). Always cross-check P/E with at least one other valuation lens.
