The week's question
In December 2024, in the thread "Re: BRK: Why Not XOM?", BreckHutHigh asked the members: "What about the long road trips with kids?" This week it is put to everyone again. The button below opens the small thread re-asking it - read what others have said so far, then give your own answer as an ordinary reply.

Ahh, all those sayings, one for every opportunity and each one´s taste. Like "Bull markets don´t die with a roar, they die on a whimper" (or similar, can´t remember). In line with Jim´s "You have a lot of time to get out ... 3 months later avarage/usually -10%" (or similar).

But does this apply to Mania´s?
Nasdaq, Feb 2000...


Good question.
Probably doesn't apply to a mania.

Digging out an old timing spreadsheet I have this for the S&P 500 at that time.

2/27/00  1409 SPX (^GSPC)
12/31/00 1289 Sell signal. down 8.5% from 2/27/00
9/16/01 966 That's the low. But we are out. Down 31.4%
3/3/02 1164 Buy signal
4/7/02 1123 Sell signal down 3.5% from 3/3/02
9/29/02 800 That's the low. But we are out. Down 31.3%
4/13/03 893 Buy signal.
12/30/07 1412 Sell signal

This was GTT timing on SPX. Worked as designed. Take a small loss and save yourself from a huge loss.
It took a loss of -9%, but avoided a loss of -31%
Then took loss of -4% but avoided loss of -31%

Here is the Nasdaq (QQQ, incl dividends) with the same timing signals.
3/8/99    42.34
2/26/00 84.47
12/30/00 49.37 sell signal Down 51.0% from 2/26/00
BUT, up 16.6% from inception 3/9/99.
9/15/01 28.84 same date for low Down 71.0% from 1/26/00
3/2/02 30.23 buy signal
4/7/02 29.07 sell signal down 9.0% from 3/3/02
9/28/02 18.02 same date for low. But we are out. Down 40.9%
4/5/03 22.03 buy signal

It took a loss of -51%, but avoided a loss of -71%.
Then took loss of -9% but avoided loss of -41%

The advice is, don't buy into a mania. Look at it from the pre-mania.
QQQ went up 2.3 times from inception (3/10/1999) to the high on 3/27/2000.

Do not buy tulip bulbs.
