Usually owning productive capital assets is a good thing to ensure reliable income stream and/or capital growth into the future.
Productive capital to me means tangible things that add to economic growth: chip factories, railroads and oil & mines (as examples).
But, in recessions, demand for goods and services declines, that usually means that productive capital assets become worth LESS for the interim. A look at recent stock prices for some capital assets is instructive:
MU (Micron Semiconductor, they make memory chips)
UNP (Union Pacific railroad) and GMT (GATX, leases railway cars)
FCX (Freeport-McMoran, large copper & gold producer)
SLB (Schlumberger, oilfield services)
All down big.
On the other hand, when the world economy recovers, there could be lots of money to be made in productive assets...
The same thing goes for productive assets, if they have a way to produce value through their use, they will equally be valued along with the good.
