Fixed up mate with stock option (3)

I haven't cracked this one yet — but the brilliant team at Times for the Times have:

Another one I’m not entirely sure about. My best take is: TUP (mate with stock option – male sheep, ram ) reversed [up]. It’s awkward syntax, ‘option’ seems odd and I’m not very happy with ‘fixed / PUT’ as the main definition. ‘Fixed up / PUT’ might be a little better, but then there’d be no reversal indicator. Later Edit: TUP (mate) reversed [fixed up] Thanks to Kevin G and others for putting me right on this one. Collins has: put – also called: put option stock exchange – an option to sell a stated amount of securities at a specified price during a specified limited period. It’s No. 20 in their list of 20 meanings, and needless to say I never heard of it.
