The one idea that saves you from bad decisions A common mistake individual investors make is reacting to a single market move in isolation—like assuming “rates up means stocks down,” or “rates down means growth always wins.” That kind of shortcut can lead to chasing performance, bailing out at the wrong time, or overconcentrating in…

The signal in one sentence The signal is SPY’s intraday range, measured as high minus low: 760.4 − 756.75 = 3.65. Why this signal matters Range is a simple, measurable proxy for how much price disagreement exists within a session: wider ranges often reflect more uncertainty and faster repricing, while narrower ranges often reflect more…

The investing myth: “If the market is up, most stocks must be doing fine.” Think of it this way: a market index is less like a town hall vote and more like a microphone. If a few very loud voices step closer to the mic, it can sound like “everyone” is speaking—even if most people…

The one idea that saves you from bad decisions A common mistake individual investors make is treating “rates up” as a simple reason to panic-sell growth stocks (or treat “rates down” as an automatic green light to chase them). That shortcut often leads to buying high, selling low, and constantly switching styles. The better idea:…

The signal in one sentence The signal is the SPY closing price, which is 759.55 (Data source: Alpha Vantage). Why this signal matters SPY is a widely used proxy for large-cap U.S. equities, so its closing level is a single-number snapshot of aggregate risk appetite in that segment of the market.

That shortcut often leads to reactive portfolio moves based on vibes rather than mechanisms. The more useful approach is to ask: which parts of the stock…

The signal in one sentence The signal is SPY’s one-session range and where the final price lands within that range, using: open 755.36, high 760.28, low 754.69, close 758.54. Why this signal matters A price session has two useful pieces of information: (1) how far price traveled (the range) and (2) who appeared to have…

The investing myth: “You need the hottest index to win” Think of it this way: most investors don’t lose because they picked the “wrong” market. They lose because they picked the right market at the wrong moment—usually after a run-up that made headlines and triggered FOMO. That’s why I like simple leadership signals. Not because…

The one idea that saves you from bad decisions A common mistake investors make is treating a move in interest rates as a “mood swing” that should automatically change what they own. That often leads to chasing whatever just worked and selling whatever just disappointed. The better approach is to separate signal from noise: rates…

The signal in one sentence The measurable signal is SPY’s closing level: 758.47 (Data source: Alpha Vantage). Why this signal matters SPY is a widely used proxy for large-cap U.S. equities, so its closing level is a compact way to track where broad risk appetite and pricing consensus landed after a full session of trading…
