Since 2006, the fund's listing. Rates compound yearly on dividend-adjusted closes; a change of side takes effect at the next close; days out of the fund earn nothing. Compare rates across funds, not dollars: spans differ. The method page has the conventions.
How often XBI crosses
XBI has crossed its 200-day average 8.5 times a year on average since Nov 17, 2006, and 70% of those crosses came within 14 days of the previous one. Waiting for three closes on the new side cuts that to 2.9 a year.
On a dividend-adjusted price series, 14 of XBI's 174 200-day cross dates (8%) would fall on a different day or not at all. This page uses unadjusted closes, the series a broker chart shows, so every date here can be checked against one.

Questions
What does "above its 200-day moving average" mean?
The 200-day moving average is the mean of XBI's last 200 daily closes. XBI is above it when the day's close is higher than that mean, below when lower. A close exactly on the line keeps the side it had.
When does this XBI page update?
After every US market close, once the day's official close is final (about 6:30 pm New York time). The dateline at the top names the last close it reflects.
What is the "confirmed on 3 closes" column?
The confirmed variant changes side only after three consecutive closes on the new side, and its cross date is the third close. For XBI it has crossed the 200-day 2.9 times a year on average, against 8.5 for the raw rule.
Which prices are used?
Unadjusted daily closes: split-adjusted, not dividend-adjusted, the prices a broker chart shows. Dividend-adjusted series put many cross dates on different days; the method page explains the choice.
