A plain-language walkthrough for first-time users. No finance background needed.
Sign up with your email, choose the stocks you care about, and reports arrive automatically.
PegSignal looks at the 100 largest non-financial companies on the NASDAQ (the "NASDAQ100" — Apple, Microsoft, NVIDIA and so on) — or, if you prefer, the broader S&P 500 (switchable anytime on the main screen) — ranks them by PEG ratio — price relative to how fast they're growing, and emails you the list. It also watches the specific stocks you pick and tells you when something changes.
A ranked list picked automatically from your chosen index (NASDAQ100 or S&P 500). You don't have to set anything up — this arrives on its own.
Only covers stocks you added to your watchlist. If your watchlist is empty, this email isn't sent.
PEG = P/E ratio ÷ growth rate. Lower means the price is smaller relative to growth.
A stock can have a high P/E ratio and still be reasonable if the company is growing fast. PEG captures exactly that: it divides the P/E ratio by how fast profits are growing. A lower PEG means the price is lower relative to that growth. We only include stocks with a PEG between 0 and 3.0, and earnings growth of 20% or more.
Three independent checks. Volume has no buy/sell direction.
Trend — is the price generally heading up or down?
Momentum — has it been bought or sold too hard recently?
Volume — are unusually many people trading it right now?
Important: these three are shown separately on purpose. They are not combined into a single score, and a green lamp is not a recommendation to buy. Think of them as three different instruments on a dashboard.
Your choice changes both how sensitive the signals are and how often selection reports arrive.
Short-term reacts quickly and emails you every trading day, but produces more false alarms. Mid-term (the default) is a balanced weekly rhythm. Long-term only fires a few times a year — going quiet for a while is normal and expected.
You can change this at any time from the main screen, and it takes effect from the next report.
The 100 largest non-financial companies on the NASDAQ — tech-heavy, and the default. Fewer stocks, so the ranking moves less from week to week.
500 large US companies across every sector, including finance, healthcare and energy. A wider net, so you'll see names that never appear in the NASDAQ100 list.
This setting only changes which index the selection report ranks. Your watchlist is unaffected — you can track stocks from either index no matter which one you pick here.
