The FTSE, as with so many others, has a nice wedge off the March lows. Like the S&P 500, the trend line from the February high to the June high remains intact. As a matter of fact, the FTSE rejected from it today.
Hmm. Wow, the very long-term chart (below) looks depressing. It has gone virtually nowhere in 20 years. Over 30 years, it has taken the form of a fairly methodical upward-sloping channel with an RSI that was not surpassed by two subsequent higher highs in price (one eked out in 2015 and a slightly more robust one in 2018).
I would expect us to revisit the lower channel, if the world markets fall apart, but perhaps that lower channel will serve at strong support (if we even get there).
