I Don't believe in #13 being an ominous omen, but the Hindenburg sign is shown on the $INDU Chart, with the top Head and shoulder pattern, Especially with the last three pull backs having lower lows.... see the 28 year Monthly chart posted eairlier, and $SPX Monthly posted in the sticky notes.... also check out the long term Monthly Charts for $COMPQ and $RUT, these two do not have lower lows with the pull backs like $INDU and $SPX.
Below is a different view of the $RUT and $COMPQ charts.
