Shape matters more than the line's height. A steady climb and a
spike-and-collapse look similar at a glance if you only read the last number.
Compare like with like. A range where the price doubles and one
where it drifts are different stories; the percentage change says more than the
price level.
Short ranges lie more. A month can look dramatic and mean nothing
over a year. Always glance at the longer range before reacting.
The past is not a forecast. A line going up is not a reason to buy,
and not evidence it will continue.
Daily closes, not intraday. Every point is one day's close, and for
foreign names the move includes the currency effect.
Informational only. Not investment, legal, or tax advice.
Daily closing prices, may be delayed, and can be wrong. Quote data:
