Calculate Final Balance Based on Initial Balance and Vector of Ratios

Description

Calculated as: initial * prod(ratios)

Usage

final.balance(ratios, initial = 10000)

Arguments

`ratios`	Numeric vector of ratios between subsequent stock prices (i.e. proportion gains + 1). For example, if a stock gained 3%, lost 1%, then lost 2%, ratios would be c(1.03, 0.99, 0.98).
`initial`	Initial balance.

Examples

# Randomly generate daily stock gains over a 5-year period
stockgains <- rnorm(251*5, 1.001, 0.02)

# Calculate final balance if initial balance was $10,000
final.balance(stockgains)
