Events & Results Calendar

Results dates change what a position is

Holding a stock through its results is a different trade from holding it the week before, whatever the chart says. The distribution of outcomes widens sharply and the technical setup that justified the position has almost no bearing on the result.

For options positions the effect is larger and works in both directions. Implied volatility rises into a scheduled event because the market knows uncertainty is coming, and it collapses immediately afterwards once the news is out. That collapse takes premium with it — which is how a correct directional view on a result can still produce a loss. The mechanism is on the Greeks page, under vega.

Ex-dates, and the drop that isn't a drop

On the ex-dividend date a stock opens lower by roughly the dividend, and that is not a fall — it is the cash leaving the company. The same applies, more dramatically, to splits and bonuses, where the price adjusts by the ratio.

Every year these produce a wave of people convinced something has gone wrong with a holding, and a smaller wave of stop-losses triggered by an adjustment that cost nobody anything. If a stock in your watchlist has moved inexplicably, this calendar is the first place to check.

Expiry is on here for a reason

F&O expiry days behave differently from ordinary days: positioning unwinds, index moves can be driven by settlement rather than by any view, and single stocks with heavy derivatives interest can move sharply for reasons that have nothing to do with the business.

Knowing which day it is prevents reading meaning into a move that has none.

What this calendar is

It is the exchange's own corporate calendar, filterable down to the stocks you follow. Companies revise dates and the exchange updates as they do, so a date here can move — always confirm anything you are trading around against the company's own filing.
