prices_rate: Calculate Growth Rate From a Vector of Prices
In stocks: Stock Market Analysis

Description Usage Arguments Value Examples

The formula is simply: prices[length(prices)] / prices[1] - 1. If units.rate is specified, then it converts to x-unit growth rate.

1	prices_rate(prices, units.rate = NULL)

`prices`	Numeric matrix with 1 column of prices for each investment (can be a vector if there is only one).
`units.rate`	Numeric value specifying the number of units for growth rate calculation, if you want something other than total growth. For annualized growth rate, set to 252 if `prices` has daily prices, 12 if `prices` has monthly prices, etc.

Numeric value if prices is a vector, numeric matrix if prices is a matrix.

# Create vector of daily closing prices for a hypothetical stock
prices <- c(100.4, 98.7, 101.3, 101.0, 100.9)

# Overall growth is 0.50%
prices_rate(prices)

# Average daily growth is 0.12%
prices_rate(prices, 1)

# Corresponds to 36.7% annualized growth
prices_rate(prices, 252)
