Did Crypto's crash or did they just have a bad hair day?

Stephen Fisher - Saturday, January 20, 2018
October 18 1987 goes down as the worst day in the US Stock Market when the S&P500 lost 22.6%.  This was nearly twice the decline experienced in 1929's 'Great Crash'.  The panic that followed occupied the financial pages for months.

On January 16, 2018, the CryptoCurrency CCI30 index of the 30 most traded currencies fell 22.9%.  But as the following list of Reuter's top news stories, the CryptoCrash did not even rate a mention.

So when is a crash not a crash?  To put it in perspective, Crypto's are volatile critters for reasons not worth mentioning here.  For instance, in 1987 the daily standard deviation of return for the S&P500 was 1.1% whereas the daily standard deviation of the CryptoIndex is 4.5%. [Standard deviation is one way of quantifying the volatility of a risky security]. 

Put simply, Crypto's are 4 times more volatile than stocks by this metric.  This means that the 22% decline in Cryptos that occured last Monday only feels like a 5% fall in the US stock market - a bad hair day certainly but not worth jumping off a building over.  A better way of thinking about it is that Cryptos would need to fall by 88% in one day for it to feel like Black Monday in October 1987 - a near total wipeout.

So punters, don't expect to hear much about CryptoCrash in the newspapers until that market effectively disappears!

We all use our spare time differently - some of us sail, some of us read and some of us spend just a little too much time working out whether that South Australian Shiraz really did deserve a gold medal


And then there are those of us who spend their spare time thinking about the better application of monetary policy, about Central Bank intervention risk and, of course, about Greece


Meet Fish, our CIO, who is almost solely responsible for keeping First Degree's lawyers constantly on standby, with his alternative (and just the right side of libelous, according to those lawyers) view of what those in power are mucking up


If you like what he writes, we are happy to take you on as a Client, because those lawyers are pretty expensive!
