Manchester United's share price in New York bounced back from an early dip in the wake of Sir Alex Ferguson's retirement announcement.
From an opening price of $18.77, the shares fell by as much as 4.5% to under the $18 mark and then revived significantly, closing at $18.44.
That left the shares down 1.76% on the day but still at a higher mark than they were last Friday, when there was no hint that Ferguson was about to call it a day.
More fluctuations are likely until United settle on their replacement for the legendary Scotsman, who has been at the helm at Old Trafford for 26 years, long before the Glazer family became involved as owners.
The IPO prospectus hinted that volatility could be on the way last August, warning success could be dependent on when Ferguson left and who came in to replace him.
Their statement read: "We are highly dependent on members of our management, coaching staff and our players. Any successor to our current manager may not be as successful as our current manager."
The visitors finished six points ahead of their opponents in the Second Division and were quickly on top, going close in the 27th minute when Ryan McCord saw his effort crash into the post, with Kevin Moon blasting the rebound over.
The Wasps' domination continued and they took the lead six minutes before the break when McCord was brought down in the area. The striker saw his spot-kick saved by Michael Andrews, but he responded quickest to tuck the rebound home.
Alloa doubled their advantage 10 minutes after the restart when Moon curled in a superb 20-yard effort.
McCord then missed a chance to make it 3-0 when he dragged a shot wide, before Kevin Cawley twice went close to reducing Brechin's deficit.
But Alloa held on and go into Saturday's return leg as firm favourites.
