As of 10:15 a.m. EDT, Castor Maritime is hanging onto a 3% gain -- but why did it rise in the first place?
The answer, in three short letters, is the BDI.
Since the start of this year, the Baltic Exchange Dry Index (BDI), which tracks the rates shippers like Castor Maritime can get for hauling dry bulk goods (e.g., coal, iron pellets, and grain) across the ocean, has been surging ever higher. From a starting point below 1,400 at the beginning of 2021, the BDI literally doubled in value through yesterday's close, at 2,808.
Castor Maritime, as an ocean-going hauler of dry bulk goods, is naturally benefiting from this trend.
And yet, if you cast your eyes across the rest of the dry bulk shipping sector today, you'll see that fellow dry bulk stocks like Danaos Corporation (NYSE:DAC) and Star Bulk Carriers (NASDAQ:SBLK) aren't enjoying nearly Castor Maritime's gains. Both are up about 1% apiece, give or take, and neither experienced anything like Castor Maritime's early morning surge.
Presumably, this has more to do with Robinhood traders and WallStreetBets mania than with anything so mundane as price performance of the BDI. In contrast to Danaos (which costs $53 and change) or Star Bulk ($18-ish), Castor Maritime is a mere penny stock that has spent the past month trading under $1. As such, it's much more subject to price swings as daytraders play its rises and slumps.
If you insist on owning it, you'd better be prepared for the kind of volatility that we're seeing today, and for outsized swings in response to any wobble in the BDI.
