¿cómo es posible que está acción con un 400% de potencial de revalorización por el valor de sus activos no esté en el fondo, que "sólo" tiene un potencial del 219%?
IAG, según Goldman Sachs, los slots de Heathrow valen más del triple que lo que cotiza:

Goldman Sachs set out how it could be worth four times its present value once the headwinds of Covid-19 ease. 
Analysts at the American bank did a “sum-of-the-parts” calculation on International Consolidated Airlines Group, working out what each bit of the business is worth and adding it up. In IAG’s case, 
-it has 200 fully owned aircraft, which Goldman reckons would still fetch about £3.3 billion. 
-Then there’s the Avios loyalty programme, said to be worth at least £1.8 billion and perhaps up to £4.5 billion. 
-By far IAG’s biggest asset is British Airways’ 2,450 pairs of summer landing slots at Heathrow, which have sold for anywhere between £15 million and £54 million over the past decade. 
At the lower end of this range, the slots are worth about £36 billion. 
Goldman acknowledges that trying to sell these slots now would be difficult, but it does “provide a way to put a value on BA’s strong market position at one of the world’s prime airports”. 
All told, all this adds up to just over £40 billion. 
Take out IAG’s pension liabilities and its debts and Goldman comes up with an equity value of something closer to £31 billion, or roughly 660p a share. 
“This is about five times [Tuesday’s] close share price and is illustrative of the group’s longer-term value potential when traffic conditions enable BA to fully use its prime slots again
