The Catapult Group International Ltd (ASX: CAT) share price had a disappointing end to the week.
The sports analytics company's shares finished the day with a decline 5% lower at $1.70.
Why did its shares sink lower?
Today's decline may be a reaction to a spot of insider selling that was revealed in a change of director's interest notice this morning.
That notice showed that one of Catapult's directors has offloaded 70,920 shares for $122,467 on market over the last few days.
While insider selling never goes down well with the market, it is worth noting that this director still holds 21,886,700 fully paid ordinary shares after this sale.
Despite today's decline, Catapult's shares are up over 30% since this time last month.
