This week's stock market nosedive doesn't appear to be letting up.

On Friday, Feb. 9, the Dow Jones Industrial Average pared earlier losses to trade higher 0.51%. The S&P and Nasdaq followed suit, up 0.7% each.

Any losses tallied by the closing bell Friday will follow up a savage Thursday, Feb. 8, that saw the Dow shed 1,033 points, or 4.15%. The S&P declined 3.75% and the Nasdaq plunged 3.9% Thursday.

As Treasury yields skyrocketed and the Cboe Volatility Index surged more than 20% Thursday, the Dow fell below 24,000 for the first time since November 2016 in its second-biggest point decline in history. The S&P dipped under its 100-day moving average and hit a new low for the week.

The stock market is on track for its worst week since the financial crisis in 2008, so what's an investor to do? TheStreet's founder and Action Alerts Plus portfolio manager Jim Cramer has been tweeting out pieces of market wisdom all Friday long.

Here are the highlights from Cramer's timeline Friday as Wall Street hunkered down for another day in the red. 

Key measure: is it painful to even look at your stocks?

Remember we are the most oversold since the January 2016 bottom...then it was the balance sheets if the oils and banks. Now it is the balance sheet of the hedge funds.

Understand that the bonds and the VIX products right now are on the side of the bulls. But the margin guys can be aggressive...

— Jim Cramer (@jimcramer) February 9, 2018

a lot of pressure to break the remaining short sellers of VIX products right here..Lot of pressure. It is amazing how many people are trying to break these clowns

— Jim Cramer (@jimcramer) February 9, 2018

the session goes to the bears if the $UXVY and $VXX and $TVIX don't stop and reverse right here. Put them on your screen. They are going to determine if there is second margin call soon...

— Jim Cramer (@jimcramer) February 9, 2018

VIX products reversing causing the stock averages to go higher. It is all cause and effect.. Need to see this rend hold to avoid 2 p.m. margin calls

— Jim Cramer (@jimcramer) February 9, 2018

Vix calms down....Margin clerks have nothing to do! Bulls win

— Jim Cramer (@jimcramer) February 9, 2018

What a dogfight right here...

— Jim Cramer (@jimcramer) February 9, 2018

they couldn't crack the market at the 2:45 post.. good sign typically to 3:30 where they have tried repeatedly and succeeded in cracking the Vix shorters. Me? i would go buy some Nvidia $NVDA right now betting that the 2:45 checkpoint held

— Jim Cramer (@jimcramer) February 9, 2018

$TVIX is in charge. if the insurgents can push this thing to $13 then it's going to be hard for the bulls to cruise in to the close. $13 is crucial and make or break for these clowns to save their hides. Just watch the $TVIX

— Jim Cramer (@jimcramer) February 9, 2018

So you can see the plan, goose the $TVIX to $13 in time for the 3:30 canvas that could cause panic on the short sellers in time to get a cascade going. Incredible how badly they want this market down.

— Jim Cramer (@jimcramer) February 9, 2018

You know what's hilarious? If a large fund that is very long goes in and blasts the $TVIX while it is teetering, we could be up several hundred points. A little money would go a long way. Blast the thing below $11 and the S&P screams higher
