Availability: Memorable Isn’t Likely
Saboteur five is a shortcut your brain takes a thousand times a day: judging how PROBABLE something is by how easily an example comes to mind. Vivid, recent, personal things feel likely; statistical, distant, boring things feel remote. In markets, that shortcut prices your fears and picks your stocks — badly.
Whatever you lived through or just watched dominates your probability estimates: survivors of a crash brace for repeats everyone else discounts; a viral story of one spectacular win makes lightning feel farmable. The actual odds never moved — only the vividness did. Memorable and likely are different properties that your intuition files in the same drawer.
Availability decides what you even consider: stocks in the news, apps you use, whatever your feed amplified — that's the tiny, loud menu most portfolios get built from, while thousands of quieter businesses never make the shortlist. This is also why we screen a universe of a thousand-plus stocks by the same yardsticks: coverage by rule, because attention by vividness misses almost everything.
The familiar is the easiest recall of all — so investors everywhere overweight their own country, industry, and employer far beyond reason. Familiarity FEELS like knowledge, but knowing a company's products isn't knowing its valuation. And the concentration lesson's warning doubles here: your job, your home, and your local-heavy portfolio can all catch the same storm.
The vivid risk — the crash documentary, the crisis just past — gets over-insured, while the statistical certainties that actually erode wealth (inflation, fees, the behavior gap itself) feel too boring to defend against. Audit your worries against the record: the disasters you rehearse are usually priced in; the leaks you ignore are usually not.
Systematic screens over story-driven shortlists. A written allocation with explicit geographic and sector diversification, so 'familiar' can't quietly become 'everything.' Base-rate checks before reacting to any vivid event — how often has this actually happened? And the one that costs nothing: stop comparing your portfolio to whoever's loudest online. Their highlight reel is availability bias, weaponized.
Vivid is not likely, familiar is not known, and the loudest risk is rarely the real one. Screen by rule, allocate by writing, and let base rates — not memories — set your odds.
