Your reasons for buying don't expire. So why stop tracking them?
Rationia remembers why you bought every stock — and re-checks the numbers for you every day. Open it any time to see exactly which of your reasons still hold.
“Sell when your thesis no longer holds.” Everyone repeats it. Almost nobody actually does it — because nobody remembers to check.
You bought because the P/E was low, growth was solid, debt was under control. Six months later? You have no idea if any of that is still true.
Rationia checks it for you, automatically, so you never hold a position for a reason that stopped being true.
Everything you need to stay disciplined
