"3 in 10 days" means the price was reached on about 3 of every 10 days like this one. Patient prices are further away and come less often; eager ones are closer and come more often. From CIEN's daily swings (about 5.8% a day lately), anchored on the Oct 14 close. The odds were measured on 10 years of S&P 500 prices (they move about 3 points from year to year with the market: bargain prices come more often in falling years, stretch prices in rising ones), and where a situation below changed them consistently (in at least 8 of 10 years), they are adjusted and marked. In those tests, waiting for the bargain price did no better on average than buying at the close: what you save when it comes, you pay when it doesn't.

Big drop and big gain: among CIEN's own worst or best 10% of daily moves, as on the Aftermath tab. The past times are history: in our tests, how a stock did after its earlier times did not predict the next one, and across the S&P 500 none of these situations leaned up or down except, weakly, an all-time high followed by a big drop. Not advice.
