Price Rate Of Change - ROC

Categories: Econ

If you don’t know what the price rate of change is and you’re an avid investor, you must be living under a rock instead of a ROC.

The price rate of change, or price ROC, is an oscillator based on price changes over time. ROC uses older prices and current prices to calculate the rate of change of a security over time.

While a ROC climbing upwards like Rocky might make you think you’re looking at a solid, bullish upward trend, you have to remember: it totally depends on the time period you’re looking at. A one-day ROC is hardly a trend. Same goes for downward-trending ROCs, showing a bearish bias.

The price rate of change is a basic tool in a technical investor’s nerdy toolbelt. Okay...it’s kind of cool. Eh...sorta.

individual items move in all different directions Prices for some

00:36

of the items might go up while prices for others

some see big jumps in price Some barely see moves

00:47

at all For instance in the past year the price

prices Right So this week all the items in your

01:31

grocery cart cost you twenty dollars Two cents That's your

01:34

general price level If you want to make an economic

01:37

indicator out of it well call it your personal general

01:39

price indicator or PGP I once you know the general

01:43

price level while you contract overall price changes over time

01:47

So a year ago the four items that you buy

01:49

every week totaled nineteen dollars Forty two cents This year

really track Honestly you're fairly er accurately in a complex

02:18

economy prices for various products are moving in different directions

02:21

all the time and a different rates all the time

extremely complicated There are a lot of competing indicators that

measure the general price levels in the overall economy The

02:33

most high profile of these is the Consumer Price index

02:37

or CP I It works like the total price is

02:40

for your weekly grocery basket except that the CP I

02:44

includes a big basket like a basket with a representative

02:47

sample off of all the stuff people by at least

02:50

all the stuff that CPS measures And it's like thousands

02:53

of things Your personal consumer price index may include just

02:56

those four items that you buy every week You know

02:59

the basket where one in four of the items are

enema tube But the C P I R consumer price
