------------------------------------------------------
And now let's look at guru Gundlach's predictions over the last 6 months:
September 11: US Treasuries will stay sustainably above 3% once long bond breaks above 3.25 pct
What happened: The 30-year bond hit 3.46%. It's now at 3.12%.
Sept 11: This might be a great time to buy commodities because they are cheaper
What happened: Unless he meant palladium or natural gas, he's off the mark
Sept 11: Global inflation has bottomed, prices now on the rise
What happened: He seems to have changed his mind
June 12: Oil to rise to $80-90 per barrel
What happened: Oil rose to $76 in October from $66 when he made the comment. It's back down below $50 now. In November he said he wasn't expecting prices to go much lower.
Nov 13: Bitcoin seems stuck at $6300
What happened: It cratered almost immediately after that. I'll give him a pass on this one because I don't think he was making a prediction, just an observation.
Nov 20: Stocks are still overbought and should be avoided
What happened: Stocks are lower. It shows he has been saying this for awhile. He said at the time that the fall looked nothing like a panic low.
Dec 11: Next move in US dollar is lower
What happened: It's too early to say.
Oct 11: US yields are headed much higher (10s above 4%)
What happened: Gundlach had really been hammering away at technical levels in the Treasury market as they broke, predicting much higher yields across the curve. They've tumbled.
Final verdict: Draw your own conclusions.
