(Sharecast News) - Insig AI was at the top of the list of buys on Tuesday, after its chairman spent almost £80k on its shares.

The AIM-traded firm said interim non-executive chair Richard Bernstein bought 275,000 shares at a price of 28.15p each, spending a total of £77,412.50.

Following the purchase, the company said Bernstein's shareholding stood at 13,167,500 shares, representing 12.46% of its current issued capital.

On the selling side of the ledger was Ultra Electronics, after its chief executive officer sold more than £1m of shares to cover the tax bill resulting from the vesting of awards.

The FTSE 250 company said Simon Pryce vested nil-cost awards over 67,452 shares, and then sold 32,616 of them at a price of 3,162.88p each.

That netted him a total of £1,031,597.77 to cover his taxes and fees.

Following the trade, Ultra Electronics said Pryce now held a total of 97,003 of its shares, representing 0.136% of its issued capital.
