Good morning Armchair Army,
Welcome to today's edition of The Armchair Analyst, a 5-minute daily update on the ASX life-sciences sector.
After over 12-months in suspension, Opthea (ASX: OPT) will hit the boards again today…
And it’s going to be ugly.
I expect heavy selling given how close it is to the end of the financial year (tax-loss sellers).
However, just like with Immutep (ASX: IMM), a trade could emerge.
I’ve worked out that with 1.37 billion shares on issue and $31 million in cash in the bank, the true cash backing is at 2.3 cents.
Now, this trade may be a bit different to Immutep.
Immutep came ‘out of the blue’...
An unexpected negative result triggered massive selling (particularly from long funds that may have been margin called on the stock).
A race to the exit.
Since Opthea has been suspended for over 12 months, there has been time to unwind these complex financial instruments and plan for today.
But, given the timing - deep into tax loss selling season - I can see this trading under cash backing.
Here is how Immutep traded on the day it fell over 95%.
It opened at 3 cents on huge volumes and slowly, over the course of the day, made its way back to cash backing:

As I press send on this, Opthea is trading at ~2 cents, still under cash backing.
Will it return to cash just like Immutep? Only time will tell.
There are a LOT of people who have their fingers on the sell button.
But also quite a few traders are ready to mop up anything that’s valuable.
Let’s see how this one plays out…
