If you look at the last 9 sessions before today's session, you find

• 2nd, 7th, 9th and 11th were share buyback days and the SP rose each day.
• 3rd, 4th, 8th and 10th were not share buyback days and the SP fell on 3 days and was unchanged on the 8th.

The SP fell strongly on the 3rd, a non buyback day after the CFO resignation was given after the close of the previous session.

The SP rose strongly on the 7th, a buyback day after an 1Q23 update was given after the close of the previous session.

No qualifications held in rocket science.
